IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 97,201, dated November23, 1869; aniedated November 17, 1869. v

To all whom it may concern:

Be it known that I, A. B. KING, of 0amden, in the county of Preble andState of Ohio,

have invented a new and useful Improvement in Cultivators; and I dohereby declare that the following is a full and exact description of thesame, reference being had to the accompanying drawing, and to theletters of reference marked thereon.

This invention relates to an improvement in that class of cultivators,&c., which employ shields for the protection of plants; and it consistsin a novel construction of shield, and also in a device for breakingdown weeds in advance of the plow, to insure the covering of the same,as will hereinafter more fully appear.

In the drawing the figure represents a side elevation of my invention.

To enable others skilled in the art to make and use my invention, I willnow proceed to describe its construction and operation.

A represents the plow-beam, to the rear end of which is attached theslanting standard B, having on its lower endthe mold-board C. At theforward end of the beam are two vertical metal strips, b-one on eachside-whose ends project sufliciently far above and below the same toadmit of their being secured by two bolts, a a. This latter arrangementforms a means of attachment for the weed-break O and the cultivator-beamD, the former of which is pivoted to the lower bolt, a, and the latterto the upper, 01. Both of these latter devices, however, are preventedfrom swinging freely by the braces d d, the former of which extends fromthe beam D to the lower bolt, and the latter from the break O to theupper bolt. The brace d is not rigidly attached to the break 0, butclasps it by means of an orifice,.through which the latter passes, andhas a free sliding motion thereon, which is limited bya projection, d onthe side of the break between the brace and the point of attachment tothe bolt a. The cultivatorbeam, being rigidly braced, has onlyalimitedmotion, such as is afforded by the vibratory motion of the strips b. Itsposition is regulated bymeans of a screw, (1 on the bolt d. The

break 0 extends back parallel with and below the plow-beam A about halfits length, when it is bent outward and extends nearly parallel with themold-board, and at its extreme end is bent downward, its function beingto break down weeds, &c., before theplow. The cultivator-beam D, whichis attached to the upper bolt, a, extends back, slanting outward anddownward nearly opposite the moldboard O, when it is bent downward atright angles and forms a standard, E, to the lower end of which isattached the cultivator-tooth e.

F represents a curved arm extending diagonally across the angle of thebeam D, to which is pivoted theshield, which-swings freely thereon, andconsists of theboot shaped piece f, to which are bolted the groovedstrips of metal f, the rear ends of which are bent inward.

The machine is held by the handles H in the usual manner.

I am aware that breaks have been em-W ployed of similar construction tomine, but differently attached. 'I am also aware that shields ofsomewhat similar construction have been used, butin all cases rigidlyattached. I do not therefore claim, broadly, either of these ideas inthemselves; but

Vhat I do claim, and desire to secure by Letters Patent of the UnitedStates, is

1. The pivoted shield f, in combination with the beam D, as and for thepurpose described.

2. The beam D, with its brace cl, constructed and arranged substantiallyas described.

3. The break 0, in combination with the brace cl and projection (1arranged and 0p erated as and for the purpose set forth.

4. The plow described, having the weedbreak, cultivator, and shield,combined and arranged as described, for the purpose set forth.

This specification signed and witnessed this 18th day of March, 1869.

A. B. KING.
